Specification of Letters Patent.

Patented Mar. 4l, 1919.

Application led October 3, 1918. Serial No. 256,707.

To all whom t may concern:

Be it known that I, GLENN D. BRLLLHART, a citizen of the United States, residing at Cuyahoga Falls, in the county of Summit and State of Ohio, have invented certain new and useful Improvements in Tire` Patches, of which the following is a speciication.

My invention relates to new and useful improvements in a tire patch and more par ticularly to what is known as a blow-out patch.

The principal object of the invention ia the construction of the patch in such a manner that it will fully cover the blow-out opening and the provision of means for securely gripping the patch for holding it in proper position.

Another object of the invention is the provision of a thin flexible strip along the longitudinal edges of the patch and applied on inside of body with a longitudinal section projecting therefrom to prevent the patch from cutting the casing or inner tubing.-

' With these and other objects in view my invention consists in the novel details of construction of parts which will be more clearly understood from the following speciwhich f Figure 1 is a plan showing my patch in position within a tire casing.

Fig. 2 is a transverse vertical section on the line 2-2 of Fig. 1.

Fig. 3 is a longitudinal section 3-3 of Fig. 1.

Fig. 4 is a perspective of a slightly modified form of my invention, and

Fig. 5 is a fragmental section on the line 5-5 of Fig. 3.

on the line In the drawings the numeral 1 indicatesl a tire casing of usual construction having a bead 2 on each edge thereof.

My patch comprises a body portion 3 conusual material employed in making patches and as is more clearly illustrated in Figs. l and 3 of the drawings the body portion of the patch is cut on a bias. The purpose of having this body por# tion cut on a bias will be later described and the advantages clearly pointed out. A divided wing 4 is secured to each end of the body of the patch and the wing is preferably formed of some flexible material such as canvas or the like. In use the wings are of the tire or ping without uncovering adapted to be bent around under the beads 2 of the casing 1 so that they may be gripped by the rimbf the wheel for securely holding in place. Y

A thin flexible strip 5 preferably rubber, which is preferably beveled, is secured to each longitudinal edge of the body 3 in the manner more particularly illustrated in4 Fig. 5 of the drawings. If the body of the patch is made in a plurality of layers this rubber strip may be inserted between two of the layers but if the body is of substantially a solid mass it may be split along the edges to receive the strip. This thin flexible strip of rubber, on the end of the patch, will prevent the patch from cutting the inner tube the casing.

In Fig. 4 of the drawings I have shown a slightly modified form of the invention in which the body portion 6 of the patch is cut straight and in this form of the invention the divided wings are indicated at 7 and the thin flexible rubber strips at 8.

The body portion of the vpatch is preferably curved to conform to the curvature of the tire casing both transversely and circumferentially. l

From the above detailed description of my patch it is thought that the advantages and mode of use will be clearly understood. It has been found that when a tire casing blows out the tear is usually on a bias. This is caused by the fact that most tires are made with the fabric in the bias and a tear will naturally follow that course.V By cutting the body portion of my patch on a bias it will readily cover a tear as is more particularly illustrated in Fig. lof the drawings. It has been Vthe common practice to construct tire patches with the body portion out perfectly straight and in doingthis it is sometimes hard to fully cover a bias tear. At the same time these patches very often slip or creep and by cutting the body portion on-a bias I al- -low for a greater amount of creeping or slipthe tear.

I' am aware that tire patches have been constructedwith a wing on the end but so far as I am aware none of-them .have been constructed with a divided wing. In applying tire patches now commonly in use it has been found that when the Wing is not divided it can not be smoothly engaged bcthem running on i irri meneer neatli the bead of the tire. By dividing the wing as I have described it can easily bel bent beneath the bead of the, tire casing although the patch, as shown, is on a bias. I also provide the thin iexible rubber strip along the longitudinal edge of the patch to prevent the edge of the patch from cutting the inner tube of the tire. At the same timel if desired these flexible strips may be made of various colors whereby to indentify patches of various makes.

The foregoing description and the drawings have reference to what may be considered the preferred, or approved, form of my invention. It is to be understood that l may make Such changes in construction and arrangement.Y and combination of parts, materials, dimensions, etc., as may prove expedient and fall Within the scope of the appended claims.

Having ully'described my invention what I claim as new and desire to secure by Letters Patent is f 1. `A tire patch comprising a body having the side edges extending at an approximately forty five degree angle to the ends.

2. A tire patch comprising a body having the side edges extending at an approximately forty five degree angle to the ends, and Wings formed on the ends of the body.

p 3. A tire patch comprising a body having the side edges extending at an approximately forty five degree angle to the ends, flexible strips inserted '1n the side edges and projecting therefrom, and wings formed on the ends of the body.

In testimony whereof I affix my signature in presence of two Witnesses.
